Serial No. 471,953.

To all whom it may concern:

Be it known that I, LENN G. MGCORRY, a citizen of the United States,residing at Carbon Center, in the county of Butler and State ofPennsylvania, have invented new and useful Improvements in Valves, ofwhich the following is a specification.

The invention relates to an improvement in valves designed for use asoutlet valves from stationary wash-basins, being particularly directedto means for automatic control of the valve.

The main object of the present invention is the provision of an outletvalve arranged to be manually operated to open the valve, a mechanicaldevice being arranged for cooperation with the valve whereby to permitautomatic closing of the valve when the waste product has entirelycleared the basin or other receptacle.

The invention will be described in the to]- lowing speciti ation,reference being had partieularly to the accon'ipanying drawings, inwhich 1* Figure 1 is a view in elevation illustrating the application ofmy improvement. Fig. 2 is broken enlarged elevation of the valve andcontrolling means, the. latter being shown partly in sect-ion. Fig. 8 isa broken sectional view partly in elevation of. the valve proper. Fig.lis a perspective detail illustrating the operation of the floatcontrolled trip. Fig. 5 is a view in elevation illustrating a slightlymodified form of the improvement. Fig. 6 is an enlarged brokenelevation, illustrating the arrangement of the float casing andconnected parts of the modified form. Fig. 7 is an elevation viewed atright angles to the view shown in Fig. 6. Fig. 8 is an elevation of astationary wash basin, showing the device arranged for manual control inboth locking the valve open and release of the lock. Fig. 9 is anenlarged broken elevation, showing the valve casing and leverconnections, the view being taken at right angles to that shown in Fig.8. Fig. 1.0 is an enlarged sectional view partly in elevation, showingthe lever locked in po-- sition to hold the valve open. Fig. 11 is asimilar view, showing the parts in position to release the lever.

Referring particularly to the accompanying drawings, the improved valvestructure is designed for use with a waste pipe 1 forming an outlet froma basin 2, which parts, aside from the details hereinafter noted, may beof any usual or preferred construction. The waste pipe at a suitablepoint below the basin is arranged to include a section of hemisphericaltype to form a valve casing 3. The wall of the casing is interiorlyprovided with diametrically opposed tlanges 4t, the space between thetree edges of which is bridged by a valve 5. The valve is of the flaptype pivotally mounted on a rod 6 arranged at the free edge of the upperpartition and projecting through a wall of the casing, the lower or freeedge of the valve being arranged to cooperate with the seat formed inthe lower flange 4, as shown. The flanges and valves divide the casinginto two chambers 7 and 8, the former of which is in directcommunication with the waste pipe between the valve casing and basin,while the latter is in direct communication with the waste pipe beyondthe valve. The casing is preferably Formed with an opening 9 closed by aremovable tap 10 whereby access may be had to the interior for cleaningor repair. On one end of the pivot rod 6 beyond the casing is fixed anarm 11 connected through the medium of a rod 12 with one end of a lever13, which is pivotally mounted intermediate its ends on a bracket 14:fixed to the underside of the plate for supporting the basin, theopposite end of the lever being connected to a stem 15 arranged toproject through an opening in the basin plate and carrying a terminalbutton 16 for convenience in operation. A spring 17 is arranged betweenthe lever and basin plate to normally hold the button-carrying end ofthe lever elevated, in which position the valve 5 is held closed. Inother words the valve 5 is normally closed by the tension of the spring17 but may be readily opened to permit the escape of water from thebasin to the Waste pipe by pressing the button 16, as will be obvious.

In conjunction with the valve described I have devised a means wherebythe valve after being manually opened is automatically closed after thewater has completely escaped from the basin, whereby the possibility ofthe escape of gases through the basin outlet is prevented and the basinis normally closed against the escape of water, permitting it to be usedfor ordinary purposes without the necessity of adjusting the valve.

With the above objects in view I provide a bypass in the escape pipeformed by pipe sections 18 of less interior diameter than that of theescape pipe and in open communication with the latter, the upper end ofthe by-pass communicating with'the waste pipe above the valve casing andthe lower end communicating directly with the chamber 7 of the valvecasing. Included in the by-pass and in open communication with valve rod6 projecting beyond the valve casing 4-, and is formed with a dependingpawl end 24;, Secured upon the rod 6 in position to be engaged by thepawl is a collar 25 having a notch or shouldered offset 26. The partsare so arranged that when the valve is fully opened in the mannerdescribed the shoulder 26 will be in position to be engaged by the pawlend 241- and the lever 22.

In operation when desired to discharge the contents of the basin intothe waste pipe, the button 16 is pressed to open the valve 5. The waterfrom the basin immediately fills the waste pipe and also the by-pass andfloat casing, elevating the float. This movement of the float causes thepawl end 2& of the lever 22 to engage the shoulder 26 on the valve rod6. The valve is thus locked in open position, and will be so heldindependent of manual control so long as water remains in the floatcasing. As soon, however, as the level of water has fallen to permit acorresponding fall of the float 20, the latter elevates the pawl end 24of the lever to release the valve rod 6, thereby permitting the spring17 aided by the weight of the connected parts, to close the valve 5against further escape of the water.

In Figs. 5, 6, and 7 I have shown a modified form of the preferredconstruction in which the outlet pipe 27 is in connection with the basin28 through a float casing 29, the pipe connections of the pipe section30 from the basin to the casing 29 and the waste pipe 27 to said casingbeing adjacent the peripheral edge of the casing orif preferred, asshown in Fig. 5, the casing 29 may include a cylindrical portion 31 andan offset cylindrical portion 32 in open communication with each other,the latter being of materially less diameter than the former and servingto provide for the connection of the pipes 27 and 30 thereto. A valvecasing 33 is connected in the pipe 27 below the float casing in which ismounted a valve,

not shown, similar to the valve 5 in the pre ferred form, the shaft 34on which the valve is fixed being connected by a rod 35 to a lever 36operated by a'push button 37 and held in normal position by a spring 38,exactly as in the preferred form. A collar 39 formed with an offsetshoulder 40 similar to the collar 25 of the preferred form is fixed uponthe shaft 3a. In the larger cylindrical portion 31 of the float casingthere is mounted a float 41 from which depends a. stem 12 through apacked opening in the.

preferred form, the advantage of the moditied form being a simplicity ofconstruction and connections and avoiding the by-pass 18 of thepreferred form. The modified form is thusbest adapted for connection inthose types of basins which are designed for public use, as the straightflow of the water to the waste pipe is less liable to accumulate refusethan is the preferred form with its bends in the by-pass. v adapted formanual operation to open the same, but when open is automaticallymaintained in such open position until the water from the basin isexhausted, at which time the valve is automatically released and closed.

In Figs. 8, '9, 10, and 11 I have shown another form of the device whichis adapted for manual control in both locking the valve The valve isthus in position and releasing the same. In this instance the waste pipe48 is provided with a valve casing 19 containing a valve, not shown,similar in all respects to that in both forms previously described. Theshaft 50 on which the valve is mounted is connected by a relativelyfixed arm 51 and a rod 52 to an operating lever 53 designed to beactuated by a push button 54: in one direction against the tension of aspring 55 similar in all respects to these features in the other formsdescribed. In this particular form it is designed to provide a meanswhereby the valve after being set in open position may be manuallyreleased, and to this end I mount in the basin plate a socket bearing 56in which is mounted a push button 57 normally spring pressed in theupward direction through the medium of a spring58, the socket bearingbeing formed with an offset or shoulder to provide a stop for the lowerend of the spring in operation. To the lower end of the push button aresecured spring arms 59, which, adjacent their upper ends, are formedwith outwardly projecting shoulders and adjacent their lower ends -withinwardly projecting shoulders 61, be-

ing below the latter shoulders inclined outwardly, as at 62, to providea flaring entrance for the operating lever. The socket bearing isprovided with a sleeve-like eX- tension 63 which extends below the basinplate and the spring arms 59 from their connection with the push buttonare inclined outwardly at (3%, the construction being such that when thepush button is in elevated or normal position under the influence of thespring 58 the inclined portion 6 of the spring arms will, throughengagement with the wall of the sleeve 63, force said arms to closedposition. In this position the flaring entrance between the arms is ofsuch size as to ust permit the passage of the operating lever 53thercthrough. The operating lever is provided at that point engaged bythe spring arms and on opposite sides with triangular projections 65,and the parts are so positioned that when the lever rides between thespring arms in the operation of said lever under the influence of thepush button 5d the projections 65 on said lever will engage the shoulderGl of the arms, thereby holding the lever in elevated position. Pressureupon the button 57 moves the inclined portion (S-l of the spring armsbelow the lower edge of the spring (33, permitting the inherentresiliency of said arms to spread the same and thereby release the lever53.

From the above construction it is obvious by pressure upon the pushbutton 54lthe lever 53 may be operated to move the valve within thecasing 59 to open position, and by the automatic engagement of'the lever53 with the spring arms 59, as previously described, the valve will belocked in open position. When it is desired to close the valve the pushbutton 57 is operated to release the lever, and the valve closes bygravity, as in the other forms.
